To determine the right foundation shade for a client, testing on the jawline is the most effective method. The jawline provides a neutral area of the face that is close to the neck, allowing for a better match to the overall skin tone, since the face and neck should harmonize for a natural appearance. Applying foundation here can help assess how it blends with both the facial skin and the skin of the neck, ensuring an even, seamless look.

Using the forehead may not provide an accurate representation, as this area can often be darker or have different undertones compared to the jawline. Matching to the wrist can lead to discrepancies, as the skin on the wrist may not accurately reflect the undertones of the client's face. Selecting the lightest shade available is not a reliable approach, as it can result in an overly pale or ashy appearance that does not complement the client’s natural skin tone. Thus, testing on the jawline is the most reliable technique for finding the ideal foundation shade.
